How to fold a Starshade Optical Shield

Posted



This fold pattern illustrates the current concept for the origami folding of the “optical shield” for the JPL Starshade.

Red lines are mountain folds, and blue lines are valley folds. The dark red and blue lines are folded almost 180 degrees, and the light red and blue lines are folded to about 30 degrees. The exact fold angles do not matter.

This pattern was created following the approach taken by Shannon Zirbel, Robert Lang, Brian Trease and others in Accommodating Thickness in Origami-Based Deployable Arrays.
